Yes. If your students each create a small object they can be laid out and printed all in one go – this can be left overnight to be finished by morning.
On small print beds -- 14cm x 14cm e.g. Up/Afinia -- you might be able to print six students’ work at a time. On larger print beds -- 28cm x 15cm e.g. MakerBot -- you might be able to print 8-10 objects at a time.
A whole class’ work could be printed overnight by running 3-4 printers simultaneously.
